Hi
Tech2 hand held support more then Opel cars.
It support also Isuzu, Suzuki, GM and SAAB
Just changing the PCMCIA card or flash it the one you have if you have only one with the softwear for cars that you need.
But this tool cannot be used with GDS2 in newer cars models after 2008 ( here we are talking in newer cars as Insignia and Astra J not the models as Corsa D 2014 wich is still supportted by the Tech 2 hand held )
GM MDI can be used as Tech2 hand held in cars from 1997 till 2014 ( but models before 2008 ) using Tec2Win emulator and can be used with GDS2 in newer models cars as Insignia and Astra J
GM MDI doesn't support Suzuki and SAAB
Booth tools suport SPS Programming
Me I'm using a HQ OP-COM clone with the lastest version of softwear wich cover even Corsa D 2014 made in february 2014 ( it covers allmost all functions of Tech2 for cars between 2004 - 2013 and better connection for cars before 1997 even it is the same tool revision B hardwear ) and an AVDI ( using Tech2win and GDS2 )

If you need a better cover my advise to you is to buy a GM MDI but the GM Tech2 hand held it is still good
Anyway in the end it is your choise-this is only my opinion
Good luck
